- _c_o_m_b generates a shell procedure [see _s_h(1)] which, when run, will
- reconstruct the given SCCS files. The reconstructed files will,
- hopefully, be smaller than the original files. The arguments may be
- specified in any order, but all keyletter arguments apply to all named
- SCCS files. If a directory is named, _c_o_m_b behaves as though each file in
- the directory were specified as a named file, except that non-SCCS files
- (last component of the path name does not begin with ssss....) and unreadable
- files are silently ignored. If a name of ---- is given, the standard input
- is read; each line of the input is taken to be the name of an SCCS file
- to be processed; non-SCCS files and unreadable files are silently
- ignored. The generated shell procedure is written on the standard
- output.
-
- The keyletter arguments are as follows. Each is explained as though only
- one named file is to be processed, but the effects of any keyletter
- argument apply independently to each named file.
-
- ----oooo For each ggggeeeetttt ----eeee generated, this argument causes the reconstructed
- file to be accessed at the release of the delta to be created,
- otherwise the reconstructed file would be accessed at the most
- recent ancestor. Use of the ----oooo keyletter may decrease the size of
- the reconstructed SCCS file. It may also alter the shape of the
- delta tree of the original file.
-
- ----ssss This argument causes _c_o_m_b to generate a shell procedure which, when
- run, will produce a report giving, for each file: the file name,
- size (in blocks) after combining, original size (also in blocks),
- and percentage change computed by:
- 100 **** (original - combined) / original
- It is recommended that before any SCCS files are actually combined,
- one should use this option to determine exactly how much space is
- saved by the combining process.
-
- ----ppppSID
- The _C_C_S ID_e_n_t_i_f_i_c_a_t_i_o_n string (SID) of the oldest delta to be
- preserved. All older deltas are discarded in the reconstructed
- file.
-
- ----cccc list A
- _l_i_s_t (see _g_e_t(1) for the syntax of a _l_i_s_t) of deltas to be
- preserved. All other deltas are discarded.
-
- If no keyletter arguments are specified, _c_o_m_b will preserve only leaf
- deltas and the minimal number of ancestors needed to preserve the tree.

- _c_o_m_b may rearrange the shape of the tree of deltas. It may not save any
- space; in fact, it is possible for the reconstructed file to actually be
- larger than the original.
